CORN-GULTIVATOR ATTACHMENT.

Application filed August 25, 1927.

tivator shovels and protecting individual plants of a crop under cultivation.

A, further object of the invention is tobefound in the provision of improved, adjustable attaching means whereby the improved attachment may be readily adapted to various makes andstyles of cultivators.

A further object of the invention is to be found in the provision of means whereby the cultivator attachment may be readily moved to inoperative position at the will of the operator. t

My invention consists in theconstruetion, arrangement and combination of elements hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing, in Wl1l0l1 Figure 1 is a side elevation of a conventional cultivator with the improved attachment in place and ready for practical use,

dotted lines indicating the attachment'in inoperative position. Figure 2 is a side'elevation, on an enlarged scale, 'of the attachment, certain parts being broken away to conserve space. Figure '3 is a rearelevation of the attachment as shown in Figure 2. Fig ure 4 is a plan view of the attachment as shown in FigureQ. Figure 5 is a fragmentary detail elevation of the attaching clamp employed to secure the attachment to the eulti vator. Figure 6 is arear elevatien of the attaching clamp in position on a cultivator beam or tongue, upper end portions o f'the attachment being shown in position on said l I t is mounted on the frame above described With the apex of the archoverlying and clamp.

tivator beams; all of which is common to the art and well known'and sub ect to 1110Cl1ll02ition and variation to produce the varying ,St yles,.types .and makes of cultivators now in general use. It is to be understood that the type of cultivator illustrated is but one of many and that the improved attachment is adapted for use with any such cultivator embodying the broad, general principles of that shown. The 1 improved attachment .CQHl-r prises a clamp member adapted for mounting on the tongue of the cultivator, a main frame .hmgedly secured to said clamp member and tines carried by said frame. The clamp member consists of two straight, similar bars or straps of metal 1%, relatlve'ly long and having each a plurality of holes throughout its length, said holes being closely spaced throughout the major-portion of the bar and the two holes adjacent one endthereof having a relatively Wider spacing. Thebar-s 14 are adapted to be mounted one on either face of the tonguell and the other bolt passng beneath said tongue, and serve to securely clampthe bars 14 against the sidesof ,said tongue, the longer portion of said bars d'ependingbelow the tongue. A- frame is shown composed of. s milar, opposed side members 16 havlngregistering holes adjacent one end, said side members being disposed in spaced, parallel relation for the 1 nia orportlon .of then length, then divergent for a space, Whereafterthespaced, parallel relation 1s resumed, each member 16' being twisted ahalf turn to, bringtheir Wider faces into the same plane, said twisted portions being connectedby a rigid brace 17 riveted or bolted at either end thereto. An angle side of the vtongue 11,"t-he end holeadjacent I iron 18 is'bent to form an angular archand bolted to the midportion of the brace 17, end port-ions of the angle iron bolted to end flange ofsaid angle iron extendingat right angles tothemembers16 adacentthe ends thereof. 1 Theframe thus formed is adapted :to be hingedto and depend from the clamp member above'idescribed, headed pins 19 being; passed through the end holesin said 1 are thus mounted to travel in parallel-verti-,

frame and opposite holes in the clamp, member and retained in the desired positlon by cotter pins The plurality of'holes in the bars 14 provides for verticaladjustment of the frame relative to the cultivator and clamp H member and increases the adaptability of the attachment. With the frame mounted as above set forth, the free flange'of the angle iron 18 extends rearwardly in a substantially horizontal plane. Spaced holes are formed in said flange and tines or spring fingers 21, each formed with an eye on one end, are

inounted through said holes and secured in positionby means of bolts passed through .said eyes and holes in the vertical flange of the angle iron. As is clearly shown in the drawing, the bolts connecting the angle iron 18 with the brace 17 and side members 16 may serve adouble purpose and be used in holding some of the tines 21." The-tines 21 cal planeslthelower. portions thereof being curved fowardly and upwardly to lie inthe same horizontal plane, said curvature :hav-

' ing varying radii to the end that the center pair of tines is positioned forwardly ofthe others and has the ends of its tinesin advvance of the restandthe-outer pair of tines is most rearwardwith the ends of its tines tothe rear'of the others. A rope, cable or the like,22, is fastened at one endto a ring or clevis 23 carriedby-the angle iron 18, the :free end of saidrope'or. cable being passed over the axle 10'to aconvenient/point within the reach'of the cultivator operator With the attachment assembled a and I Imounted'as illustrated and" above described,

"ground and it is in position for use.

the rope or cable 22 being slack, the weight of the'attachment causes it. to swing forwardly and" downwardly until the forward portions of the tines21 contact with the As the eultvator' is moved throughthe field and 0perated in the usualiand customary manner the attachment m'oves'along the row of plants being cultivated-Ihalf of {the tines 21 being -.on either sid'eofjsaid row and when vines f are encountered'gi'owing on saidfplantsthey are lifted by thetines, stripped from the plants and moved outwardly along the tines V away from said row.

Should any fixed obstruction, such as a 'arock or stump, be encountered, the attachrqinent'is free to swing to the rear and pass over thesafmed When the crop is too high to pass under the attachment, or when turning-* a v at the; end of a row, -the operator may lift theattachment out of operating position by .ineanso'f therope orlca bl'e 22.

As many ehanges ofstructure and arrange ment are possible without departing from the spirit of my invention, I wishto be understood as being limited solely"bythe scope ofthe appended claims. I
